Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an onigiri packaging sheet in which a sheet-like food such as a sheet of laver is sandwiched between an inner film and an outer film, and a packaging rice ball packaged with the packaging sheet.

[0002]

2. Description of the Related Art In such a packaging sheet, a sheet of laver is sandwiched between a rectangular outer film and an inner film formed of two film pieces.

As shown in FIG. 9, one side of a triangular onigiri rice is placed on the inner side of the packaging sheet at a substantially central portion in the longitudinal direction, and the triangular onigiri rice is covered with the sheet.

[0004] The four corners of the overlapped sheet are folded back on the back of the triangular rice ball and fixed by heat welding or a sealing piece.

[0005] When eating rice ball rice, pull the knob (11) formed on the top of the surface of the packaged rice ball to the bottom side of the triangle rice ball, and then pull the outer film (1) from the back side of the triangle rice ball to the top. Tear in the longitudinal direction and pull left and right.

[0006] Each of the film pieces of the inner film is also pulled right and left together with the outer film, so that the sheet-like laver directly covers the rice ball.

[0007]

When the product name or the like is printed (10) on the outer film (1) of the packaging sheet, there is a problem in that the outer film is divided into two by pulling the knob (11). However, as shown in FIG. 10, in the case of a wrapping rice ball in which a label (7) on which a product name or the like is printed is stuck on a plain outer film (1), a thin piece formed by pulling a knob (11) is formed. The strip-shaped tearing piece (12) becomes thinner afterwards due to the resistance when passing through the label (7) and breaks in the middle, so that the outer film cannot be divided into two sides and the packaging cannot be unraveled. It is one after another.

[0008] The present invention is to clarify a packaging sheet capable of solving the above-mentioned problem and a rice ball wrapped with the packaging sheet.

[0009]

The packaging sheet of the present invention has a sheet-like food (8) sandwiched between an outer film (1) and an inner film (2), and the inner film (2) is composed of two films. Piece (21) (2
1) is formed by overlapping the opposing sides at a substantially central portion in the width direction of the packaging sheet, and is symmetrically formed at the substantially central portion in the longitudinal direction and the width direction of the outer film (1) from the central portion to both ends in the film longitudinal direction. Knobs (9) and (9) are provided for tearing
(9) is formed by a score line (90) penetrating the front and back of the film.

The rice balls wrapped in the above-mentioned wrapping sheet are placed on a triangular onigiri rice (4) at a substantially central portion of the wrapping sheet so that one side thereof is orthogonal to the longitudinal direction of the wrapping sheet. Of the triangular rice ball (4) from the top to the center of the opposite side.

[0011]

[Operation and Effect] The tabs (9) and (9) for tearing the outer film (1) are provided at substantially the center in the longitudinal direction of the film. Since the sheet is placed and wrapped so as to be orthogonal to the longitudinal direction at substantially the center in the longitudinal direction of the sheet, when the wrapped rice balls are displayed with the triangular surface front and rear, the knob (9) is placed on the bottom of the rice ball. It will not hide, and the knob (9) will not impair the appearance of the packaged rice ball.

[0012] In addition, when selling the packaged rice balls,
If the packaged rice ball is displayed so that (9) is located on the bottom side of the rice ball, the score line (90) for forming the knob (9)
The sheet-like food can be prevented from getting wet by preventing outside air from entering from the outside.

When eating rice balls, the picking portions (9) and (9) of the packaging rice balls are pulled to the top on the front side and the top on the back side of the packaging rice balls.

Labels (7) on the front and back of the rice ball
Even if the extension (70) is attached and the extension of the knob (9) is torn, the extension from the label (7) to the top of the rice ball is short. It reaches the top by the time it cuts, and the outer film (1) can be split into two sides.

When the outer film (1) divided into two is pulled right and left, each film piece (21) (21) of the inner film (2) is
It is pulled together with the two film pieces (11) and (11) of the outer film (1) to be separated, and slides out from between the sheet-shaped food (8) and the rice ball (4) to leave the rice ball (4). .

Thus, the sheet food (8) directly covers the rice ball (4).

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, the packaging film has a sheet-like food (8) such as a sheet of laver sandwiched between an outer film (1) and an inner film (2). In this case, an intermediate film (3) is interposed between the outer film (1) and the sheet-like food (8).

The outer film (1) is a substantially directional film having a length of about 220 mm and a width of about 140 mm and having a substantially rectangular shape and easily tearing in the longitudinal direction.

The outer film (1) has two knobs (9) and (9) at substantially the center in the longitudinal direction and the width direction, respectively, for tearing the film along the longitudinal direction.

The knobs (9) and (9) shown in FIGS. 1 and 2 are formed by making cuts (90) in an H shape through the front and back of the film.

The length of the parallel vertical lines at both ends of the cut 90 on the H-shape is about 5 mm, and the length of the horizontal line at the center is 5 to 15 mm. The horizontal lines extend along the width direction of the outer film (1), and the parallel vertical lines extend along the longitudinal direction of the outer film (1).

The inner film (2) is formed by superposing a pair of substantially rectangular film pieces (21) and (21) on their side edges along the longitudinal direction of the film pieces (21) and (21) by about 7 mm. Formed,
It is a size that exactly overlaps with the outer film (1).

In the embodiment, a point weld (22) is attached to the central portion in the longitudinal direction of the overlapping portion (20) of both film pieces (21) and (21) of the inner film (2) so as to be easily peelable. I am giving.

The intermediate film (3) has a length of about 220 mm as in the case of the inner and outer films (1) and (2), and a width of the outer film.
It is slightly larger than half the width of (1).

The intermediate film (3) and the inner film (2)
It is formed by a moisture-proof film.

The outer film (1) and the inner film (2) are overlapped with their contours aligned, and an intermediate film is interposed between the two films (1) and (2).
(3) with one side edge along the longitudinal direction of the film inside and outside
(1) The outer peripheral edge is thermally welded by sandwiching it so as to coincide with one side edge along the longitudinal direction of (2).

The heat welding is not performed on the entire outer periphery of the laminated film, but on the film pieces (21) and (21) of the inner film (2).
And its vicinity including the overlapping portion (20) are excluded.

At a substantially central portion in the longitudinal direction of the inner film (2) of the packaging sheet (7), one side of the triangular rice ball (4) is placed orthogonal to the longitudinal direction of the sheet. A sheet is put on both sides, wrapped in the same procedure as the conventional example of FIG. 9, and a label (7) on which a product name or the like is printed on the triangular surface is attached as shown in FIG. Attach the back label (70) printed with the date of manufacture.

The knobs 9 and 9 of the outer film 1 are located on the bottom of the rice ball 4.

However, the tabs (9) and (9) for tearing the outer film (1) are provided substantially at the center in the longitudinal direction of the film, and the rice ball (4) is packaged on one side. Since the sheet is placed and wrapped so as to be orthogonal to the longitudinal direction at substantially the center in the longitudinal direction of the sheet, when the wrapped rice balls are displayed with the triangular surface front and rear, the knob (9) is placed on the bottom of the rice ball. It will not hide, and the knob (9) will not impair the appearance of the packaged rice ball.

If the knob (9) is displayed so as to be located on the bottom side of the rice ball, outside air can be prevented from entering through the score line (90) for forming the knob (9). Moreover, as in the embodiment, the score line is cut by the intermediate film (3).
By preventing the invasion of the outside air from the (90), it is possible to more effectively prevent the sheet-like food (8) from getting wet.

When eating rice balls, the picking portions (9) and (9) of the rice balls are pulled to the top on the front side and the top on the back side of the rice balls.

Labels (7) on the front and back of the packaged rice ball
Even if (70) is stuck and the extension of the knob (9) becomes tear-resistant, the extension becomes thinner because the distance from the label (7) to the top of the rice ball is short. The top of the film (1) can be divided into two sides to the left and right by the time it is cut.

When the outer film (1) divided into two is pulled right and left, each film piece (21) (21) of the inner film (2) is
It is pulled together with both film pieces (11) and (11) of the outer film (1) to be divided into two, and the sheet food (8) and the rice ball (4)
Slide out from between and move away from rice ball (4).

As a result, the sheet-shaped food (8) directly covers the rice ball (4).

FIG. 7 shows another embodiment of the knob (9) of the outer film (1).

In FIG. 7A, one horizontal line of the H-shaped cut line (90) is interrupted. The break (91) can prevent the knob (9) from being turned up naturally before unpacking.

FIG. 7 (B) is a view in which both ends of the cut in the horizontal direction are cut in the vertical direction perpendicular to the cut and in mutually opposite directions. In FIG. 7B, both cuts in the vertical direction can be omitted and only cuts in the horizontal direction can be made.

Since the outer film (1) has a property of tearing in the longitudinal direction, the film can be torn from the bottom to the top of the rice ball as shown in FIG. 6 without extending the lateral cut. .

FIG. 7C shows an X-shaped cut, and
One of the knob portions (9) and (9) is formed.

FIG. 8 shows the use of a well-known cut tape for cigarette packaging, that is, a means for joining a thin tape made of a resin film to a film and pulling one end of the tape to tear the film.

The cut tape (92) is applied over the entire length in the longitudinal direction through a substantially central portion in the width direction of the outer film (1), and is cut at the knob (9).

When the knob (9) is pulled, the cut tape is also pulled at the same time, so that the outer film can be beautifully divided into two. In this case, it is not necessary to use a directional film having a fixed tear direction as the outer film.

The present invention is not limited to the configuration of the above embodiment, and various modifications are possible within the scope of the claims.
